![]() ![]() All of Liberty Ammunition’s loads are within SAAMI specs for pressure and dimensions. References to ZZ Top aside, many people are understandably concerned about the pressures produced by high-velocity cartridges. ![]() I have to wait until the 2015 SHOT Show like everyone else. There are rumors of additional loads coming out in the near future, but unfortunately not anything I can confirm or deny. Liberty Ammunition currently offers six handgun loads in the Civil Defense line. Federal Premium uses polymer as a jacket for their Nyclad bullets. A variety of alloys (mostly aluminum-based if I recall correctly) have been used by Winchester Ammunition to jacket their Silvertip line of hollowpoints. Using a non-copper bullet jacket is not a new idea. ![]() It also has the side benefit of eliminating copper fouling of the bore. This allows the bullet to travel faster on the same powder charge. By jacketing the copper bullets in nickel, friction in the barrel is reduced. Nickel, on the other hand, is well respected for its lubricity. Even so, copper is used to jacket lead bullets because (1) lead is even softer and stickier than copper, and (2) copper is still soft enough to make it easy to work with. Copper is a relatively (for metal) sticky material. The color comes from the nickel jacket that is used in bullet construction. Looking at the rounds, the silver color of the bullet jumps out at you. The huge hollow area allows the load to maintain the correct overall length for the caliber while keeping the bullet much lighter than one would ordinarily expect. The Civil Defense bullet is a monolithic copper design with a very deep hollowpoint. ![]()
